- Jenkins ver. 2.78
- openjdk version "1.8.0_141"
I am running jenkins using vagrant inside CentOS 7.
It worked fine after changing my machine from Mac OS to Ubuntu & upgrading the blueocean plugin to "1.3.0-beta-2".
The reason could be proxy or some other setting which was not allowing the communication to happen.
Since it took fair amount to time to debug, I hope someone else doesn't waste their time & check their machine configs before putting a bug.
